The two biggest fears behind the wheel of a big rig are taking a wrong turn into a low bridge and being blamed for something you didn’t do. A truck GPS with a built-in dash cam tackles both at once — it routes you around clearance and weight problems, then records the drive in case you ever need to prove what happened.
I’m Mo Maruf — the founder and writer behind GoCarLife. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
If you drive a truck for a living, you need routing that respects your rig’s size and a camera that records what happens around you. These six units pair custom truck routing with an onboard camera, and the crowd favorite — around 4.4 stars from 900+ owners — shows what a dependable truck gps and dash cam should do on the open road.
Our Picks at a Glance
How To Choose The Best Truck GPS and Dash Cam
Before you compare screens and cameras, know that a standard car GPS can be dangerous in a truck — it doesn’t know your height, weight, or hazmat restrictions. A truck navigator uses your rig’s actual dimensions to steer you clear of low bridges, tight curves, and roads you legally can’t use. That routing difference is the core reason to choose a truck-specific unit over a car GPS.
Truck routing depth matters more than brand name
The best units let you enter your truck’s size, weight, and cargo — including specific trailer types and axle counts — then build every route around those limits. Some also flag bridge heights, sharp curves, steep grades, and engine brake restrictions along the way. If a unit can’t do that, it’s just a car GPS with a bigger screen.
The dash cam is your eyewitness
You want a camera that records in clear high definition and captures a wide field of view, so it sees more of what’s around you. Automatic incident detection is the key feature — it saves footage of a sudden event on its own, so you don’t have to remember to hit record. Some units store that video securely in an online vault you can reach from your phone.
Screen size and cab space are a trade-off
A larger display is easier to read at a glance, but it takes up more windshield and dash space in an already crowded cab. Eight and ten-inch screens show more map detail and look sharper, while seven-inch units are more compact and still perfectly readable. Think about where it will actually sit before you commit to a size.

In‑Depth Reviews
1. Garmin dēzlCam™ OTR725
Our pick — over 4★ from 60+ verified ratings; the strongest balance of quality and price.
The 7-inch eyewitness that pairs proven routing with a wide-angle dash cam.
This pick balances everything a working driver actually needs. The built-in dash cam records in 1080p HD (high definition, 1920×1080 pixels) with a wide 140-degree field of view, so it catches more of what happens around you — and it automatically saves incident video to the pre-installed memory card, meaning you don’t have to press anything when things go wrong.
On the routing side, you get custom truck navigation based on the size and weight of your rig, with alerts for upcoming bridge heights and sharp curves. The 7-inch LCD touchscreen is bright and crisp for in-cab viewing, and the BirdsEye Direct Satellite Imagery gives you high-resolution overhead views of loading docks and truck entrances before you arrive.
Buyers report the truck-specific routing and accurate maps are the standout traits, and that it feels faster than the older OTR710. The recurring gripe is the dash cam’s memory card — one owner wrote, “But have to keep reformatting the sim card for the dash cam to keep it working which sucks” — so treat the card as a maintenance item rather than a set-and-forget part.
What wins people over
- 140-degree, 1080p dash cam with automatic incident saving
- Truck-specific routing with bridge height and curve alerts
- BirdsEye satellite views of docks and truck entrances
- Community-shared truck parking and CAT Scale locations
The trade-off to know
- Dash cam may need frequent memory card reformatting
- Some features require the dēzl app and a Bluetooth connection
Reach for this if: you want one dependable unit that handles both routing and evidence capture without fuss.
Plan for: occasionally reformatting the dash cam’s memory card to keep recording working.
2. Garmin dēzlCam™ OTR710
Records the incident, then locks the footage away in an online vault.
The OTR710’s a neat extra is where your dash cam video goes after a crash. It saves incident footage automatically, then stores it securely in the online Vault — so even if the memory card is damaged, you can still pull the proof from your phone through the dēzl app. For a driver whose livelihood depends on the record, that’s a serious layer of protection.
The 7-inch touchscreen is bright and high-resolution, and routing is custom to your truck’s size and weight, with alerts for bridge heights, weight limits, sharp curves, and steep grades. Arrival planning uses BirdsEye Satellite Imagery so you can scope out loading docks and security gates before you get there.
Owners say it’s easy to update and simple to connect to a phone for quick address transfers, and the route planner is praised for spotting good places for fuel stops and overnight breaks. The honest caveat is that a small share of units have disappointed — one buyer found the directions unreliable and the return process frustrating — so it’s worth testing the routing carefully in the first few weeks.
Why it stands out
- Incident video is stored in a secure online Vault
- PrePass weigh station and bypass notifications
- Forward collision and lane departure warnings
- North America map updates with Mexico and Canada coverage
Keep in mind
- An occasional unit arrives with routing that misses the mark
- Weighs 9.56 ounces, a touch heavier than the OTR725’s 8.5 ounces
Best for: drivers who want crash footage stored safely off-device in case the card fails.
Look elsewhere if: you’d rather not depend on the app and Bluetooth to open up the full feature set.
3. Rand McNally TND 1050
A huge, rugged 10-inch screen that refuses to quit on rough roads.
If readability is your top priority, this is the one. The 10-inch high-definition display is the biggest in this lineup — dwarfing the 7-inch Garmin units — and it’s protected by heavy-duty Gorilla Glass (a tough, scratch-resistant glass) plus a removable protective guard, so it’s built to survive the daily punishment of life in a truck.
Rand McNally claims 33% more truck-specific road data than other GPS providers., meaning routing is customized for your rig’s size, weight, and cargo. The integrated dash cam handles driver and vehicle inspection reports, and receipt tracking keeps your expenses organized without a separate app.
Owners love the magnetic dock that lets you pull the tablet out easily, and the WiFi updates keep the road atlas current. The main knock is the size itself — one driver called it “HUGE!” and noted the graphics could be sharper, plus a few found the navigation occasionally sends them miles out of the way for a gas station that was right there.
The big wins
- 10-inch HD display with Gorilla Glass protection
- Road atlas updates over WiFi or hotspot
- USB port to charge devices on the go
- Receipt tracking built right into the workflow
Where it stumbles
- Some owners mention navigation quirks like unnecessary exits
- Large footprint takes up serious cab and windshield space
Reach for this if: you want the easiest screen to read at a glance and don’t mind the bulk.
Acknowledge: the routing isn’t flawless for every owner, so give it a solid test run.
4. Rand McNally RANDTAB8
The affordable sixth-generation navigator that still customizes routes to your truck.
It delivers custom truck routing at a budget price. The TND 750 is a sixth-generation truck GPS with a 7-inch LCD screen that stays easy to read even mounted on the dash, and it customizes routing based on your truck’s size, weight, and cargo. Dynamic weather overlays show precipitation, temperature, and wind speed right across your route.
It also adds 3D buildings and landmarks, so you can follow detailed routes through areas rendered with recognizable structures instead of flat lines on a map. Bluetooth and lane assist round out the feature set, and the screen is big enough to glance at without leaning in.
Owners appreciate the readable screen and the truck-customized routing — one driver said it works as a truck GPS for trucking routes just as needed. The honest reality is that routing can get confused: “Will not recalculate for 30 miles down the road” is a real complaint, and some find the search function less intuitive than they’d like. It’s a solid budget option with occasional routing quirks.
The value case
- Custom routes based on truck size, weight, and cargo
- Weather overlays with precipitation and wind speed
- 3D buildings and landmarks for easier navigation
- Easy-to-read 7-inch display
The honest limits
- Recalculation can lag far behind when you leave the route
- Search interface takes getting used to
Best for: budget-conscious drivers who need solid truck routing and can accept a few quirks.
skip it if: you depend on instant route recalculation when you miss an exit.
Understanding the Specs
Truck-specific routing
This is the spec that separates a truck GPS from a car GPS with a big screen. It takes your rig’s size, weight, and cargo — sometimes down to the exact hazmat type and trailer length — and builds routes that avoid low bridges, tight roads, and legal restrictions. A unit without it can route you into a bridge strike.
Dash cam resolution and field of view
Resolution determines how clear the footage is, and field of view determines how much of the road you capture. A 1080p HD camera with a 140-degree field of view catches more of the environment than a narrow-lens camera. Automatic incident detection is what saves the footage without you touching anything.
